4-1. Paper Path

Paper can be fed into the printer either from the Multi-purpose Tray (PagePro 1200W: 150 sheets;

PagePro 1250E 200 sheets) or Manual Feed Tray.

The paper feed system can be extended to a 3-way system by Installing the Second Paper Cassette

Unit (500 sheets).

The paper fed by the Paper Take-up Roller is transported to the Image Transfer Roller, Fusing Roller

and then Paper Exit Roller. After this, the paper is fed out onto the Print Tray

4-2. Paper Take-up Section

(1) Multi-purpose Tray

Mechanism

• When the Paper Take-up Solenoid is energized, the drive of the Main Motor is transmitted to the
Paper Take-up Roller via the Paper Take-up Gear (one-way clutch) to turn the Paper Take-up
Roller one revolution.

• At the same time, the Depressing Cam turns and lifts the Paper Lifting Plate, and the first (top)
sheet of paper on the tray is fed to the printer.

• The Fixed Separating Pad is used for the paper separation system. It prevents the second and sub-
sequent sheets of paper from being fed together with the top sheet.

• The actual length of the paper is detected using the period of time through which the Paper Take-
up Sensor remains energized (or through which the paper moves past the sensor) and it is deter-
mined whether the actual length matches the paper length specified by the controller.

Paper Empty Detection

There is a Paper Empty Sensor provided on the upper side of the Multi-purpose Tray. It functions to

detect a paper-empty condition in the Multi-purpose Tray and the Manual Feed Tray.

When there is paper, the actuator is raised and thus the sensor light is blocked.

When paper runs out, the actuator drops into a cutout in the tray, thus unblocking the sensor light.

(2) Second Paper Cassette Unit (option)

Mechanism

• Since a drive motor is not installed in this unit, the drive of Ml is transmitted to the paper take-up
and transport sections in the unit via the Drive Transmission Gear.

• Although the feeding method is the same as the Multi-purpose Tray in the printer, the corner sep-
aration system is employed in this unit as the paper separating method.

• Paper is separated at the corner by the paper separation finger in the paper cassette and the
strength of paper itself (corner separation system). One sheet of paper is fed for each paper take-
up cycle.

• The Paper Take-up Solenoid (SL21) in the unit is controlled by the printer via PWB-A in the unit.

Cassette Type Detection

The Second Paper Cassette Unit is provided with a Cassette Type Detecting Switch that comes with
a lever.

When the paper cassette is slid into position, the projections on the right-hand side of the cassette
push the lever according to the size of the paper loaded in the cassette, thus turning off or on the Cas-
sette Type Detecting Switch.

The Cassette Type Detecting Switch consists of three subswitches. The combination, in which these
subswitches are turned on and off, allows the printer to determine the cassette type (or the paper
size).

(1) Overview

• The PC Drum is charged with static electricity before laser exposure.

• The Drum Charge Brush and the Pre-charge Film are used for the charging method.

• The Drum Charge Brush and Pre-charge Film charging generate little ozone in the printer.
Because the charge is directly applied to the PC Drum, the PC Drum can be charged by low volt-
age. At the same time, the PC Drum can be charged stably and evenly.

• The Pre-charge Film supplies the charge to the PC Drum before being charged by the Drum
Charge Brush to improve the charging efficiency.

• The Drum Charge Brush is turned by the drive of the Main Motor (Ml) via a gear.

• The electric potential on the surface of the charged PC Drum is approximately-800 V.

4-4. Laser Exposure

Laser exposure is the process of creating an invisible static charge image on the PC Drum by the

laser beam emitted from the Print Head Unit.

This process is controlled as follows in order to appropriately time image printing.

Print Head Unit

PC Drum

In the sub-scanning direction (vertical direction)

• When the printer receives the PRINT signal, the Polygon Motor and the Main Motor rotate and
the paper is fed into the printer.

• The printing in the sub-scanning direction is started when the Controller Board sends the VIDEO
signal to the Print Head a certain time after the leading edge of the paper activates the Paper Sen-
sor (TOD signal).

• The print starting position for the 2nd line is decided by delaying the VIDEO signal sending tim-
ing.

In the scanning direction (horizontal direction)

• The SOS Sensor is installed on the Laser Diode Control Board to unify the laser emission timing
for each scan line.

PRINTING AREA

• The controller sends the VIDEO signal at the appropriate paper size to the engine (Controller
Board).

• The controller determines the start point of printing according to the TOD signal (sub-scanning
direction) sent from the engine (Controller Board) and the HSYNC signal.

• Laser exposure is started when the print head receives the VIDEO signal.

4-6. Image Transfer

(1) Overview

• Image transfer is the process of transferring the toner image created on the PC Drum in the devel-
oping process to paper.

• Roller image transfer is used instead of corona image transfer as the image transfer method.

• In roller image transfer, there is little generation of ozone due to corona discharge. Also, there is
no blur of toner because the paper is always pressed by the PC Drum and the Image Transfer
Roller.

• When cleaning the Image Transfer Roller and before printing, reverse bias is applied.

• The residual electric potential on the paper is dissipated via a discharge needle.

PagePro 1200 Series Mechanical / Electrical

(1) Overview

• The toner image transferred onto the paper is securely fixed to the paper.

• A heat roller system is used as the fusing system. The toner image is fused by the Heat Roller
heated by the Heater Lamp, and securely fixed by the pressure between the Heat Roller and
Backup Roller.

(2) Fusing Temperature Control Circuit

• The Thermistor detects the surface temperature of the Heat Roller and inputs that analog voltage
into IC1. Corresponding to this data, the Heater Lamp ON/OFF signal is output from IC1A-55,
causing the Heater Lamp to rum ON or OFF to control the fusing temperature.

• When the Heater Lamp is not turned OFF even if the Thermistor detects a high temperature mal-
function (if the surface temperature of the Heat Roller exceeds 230°C), the signal from IC1-79
changes from L to H to turn OFF the Heater Lamp forcibly.

up and the Heater Lamp turns ON. The Heater Lamp remains ON until the temperature of the Heat
Roller becomes about 160 C, providing the following temperature control.

Mode 1

The temperature is controlled to maintain about 160°C during printing and about 125°C (PagePro
1250E) or 115°C (PagePro 1200W) during standby. This mode lasts 300 seconds (PagePro 1250E)
or 90 seconds (PagePro 1200W) seconds before the control shifts to mode 2.

Mode 2

This mode lasts for 208 seconds before the control shifts to mode 3.

The temperature of the Heat Roller gradually falls from about 160 C to about 155 C.

Mode 3

The temperature is controlled to maintain at about 155°C during printing and at about 125°C
(PagePro 1250E) or 115°C (PagePro 1200W) during standby. This mode is maintained unless an
error occurs or the Top Cover is opened.

3) Instructions for Handling the PWBs with MOS ICs

The following precautions must be observed when handling circuit boards with MOS (Metal Oxide
Semiconductor) ICs.

During transportation or when in storage, new circuit boards must not be indiscriminately

removed from their protective conductive bags.

Do not store or place circuit boards in a location exposed to direct sunlight.

When it becomes absolutely necessary to remove a board from its conductive bag or case, always

place it on its conductive mat in an area as free as possible from static electricity.

4) During Replacement the PWBs with MOS ICs:

Before unplugging connectors from the circuit boards, make sure that the power cord has been

unplugged from the power outlet.

When removing a board from its conductive bag or case, do not touch the pins of the ICs or the

printed pattern. Place it in position by holding only the edges of the board.

Before plugging connectors into the board, make sure that the power cord has been unplugged

from the power outlet.

5) During Inspection the PWBs with MOS ICs:

Avoid checking the IC directly with a multimeter; use connectors on the board.

Never create a closed circuit across IC pins with a metal tool.

Where it is absolutely necessary to touch the ICs and other electrical components on the board, be

sure to ground your body.

6) During Transportation/Storage the Drum Cartridge:

Use the specified carton whenever moving or storing the Imaging Cartridge.
The storage temperature is in the range between -20°C and +40°C.

7) Handling the Drum Cartridge:

The PC Drum is extremely sensitive to light shock and takes long time to recover sensitivity.

Never open the protection cover or expose the PC Drum to direct sunlight for long periods of

time.

Do not to contaminate the surface of the PC Drum with oil-base solvent, fingerprints, and other

foreign matter.

Do not scratch the surface of the PC Drum.

7-1. Paper Misfeed Detection

(1) Overview

The printer determines if paper is left inside itself by detecting the status (H or L) of the signal out-
put from the Paper Take-up Sensor (PS1) and the Paper Exit Sensor (PS3).

A paper misfeed while paper is being transported is detected by monitoring the timing at which the
signal from the Paper Take-up Sensor (PS1) or the Paper Exit Sensor (PS3) rises or falls.
When a paper misfeed is detected, the drive for all elements is stopped.

• During multi printing:

If there is paper being transported through the printer when condition 2 listed below is detected, all
elements but the Heater Lamp (HI) will be stopped after the paper has been fed out of the printer.

• During single printing:

When only condition 2 listed below is detected, all elements but the Heater Lamp (HI) will be
stopped.

(2) PagePro 1250E Paper Misfeed Detecting Conditions
